So... it says those are 105 foot squares. That's a very odd choice, and that would make those flowers really huge, even by fantasy giant flower standards, so I'm guessing that's probably a mistake?

This section is mostly underwater, right? It looks underwater to me.

Putting a village into a cavern complex is cool. What you show here is both dark and spookily glowing, so I think it would help put players a bit on edge wondering about those odd cracks of light in the stone and those strange glowing flowers and is there something down there at the bottom of that depression!

If you have a canyon, at least have the option of a precarious rope bridge spanning it.
